Across two of Nintendo's biggest markets, the US and Europe, the house that Mario built has managed to get a lot of its hardware and software into customers' hands, reporting huge sales milestones and a very prosperous December. In Europe, the DS is now the best-selling video game console of all time, surpassing the 40 million mark in the region. The Wii now tops 20 million, becoming the fastest-selling console in the region since its release three years ago. There's also some data on Nintendo's games to chew on, including Wii Sports Resort, which sold five million since releasing in July, and New Super Mario Bros. Wii, which just reached 2.5 million units sold.
As for the States, Nintendo's been raking in equally impressive amounts of cash here. In December, three million Wii consoles were purchased and the DS set "a new all-time calendar-year U.S. sales record for any console or hand-held system." You know, just like the company did last year. Also, New Super Mario Bros. Wii had quite the stellar showing in the U.S., achieving lifetime sales of four million units in the region.
In short: Nintendo is pretty much the same as always.
